. POWER-DRIVEN BRUSH.

Application filed December 27, 1923. Serial No. 682,932.

7 My invention is an improved powerdriven brush, particularly adaptedfor cleaning walls, ceilings, Woodwork, etc. r

The object of my invention is to provide a brush which is simple inconstruction, and inexpensive to manufacture. I

Another object is to provide a detachable handle or stand; so that thebrush may be portable for the uses outlined above, or stationaryfor useas a clothes brush, etc.

In the annexed drawing in which my invention is illustrated; Figure 1 isa side view of my brush.

Figure 2 is a fragmentary sectional View of the handle mount for thebrush.

Referring more particularly to the drawing, an electric motor 1 hasflanges 2 and 3 formed at either end thereof. A tubular handle 4: has aflange 5 formed on the end thereof, which is bolted against the flange 3of the motor, thus securing the motor to the handle. A tube 6 has aflange 7 on the lower end thereof, to Which the flange 2 is bolted. Theshaft 8 of the motor 1 extends through the tube 6 and a coupling 9 issecured to the outer end thereof.

The cleaner 10, which is preferably conical in shape, is mounted upon ashaft 11, and this sh aft extends into the coupling 9 thereby securingthe brushto the shaft 8, which shaft causes the cleaner"torotatem partlyin section A locking pin 12 is pivoted to the lower end of the handle l,and extends through a hole 18 in the handle. The stand 14 has a shank'15 extending into the handle 4, and the pin 12 extends into the shank,thus holding the brush in the stand. By removing the pin the stand 14may be removed and the shank 16 of the hand grip-17 inserted in its 40place. 7 It Will be understood that the invention is not limited to theexact structure disclosed, and that various modifications may be madeWithin the scope of the appended claim. I have therefore used the termsupporting member to indicate the stand 14;, the hand grip 17, and theirmechanical equivalents.

Having described my invention, I claim:

A power driven brush comprising 'a handle, a flange on the outer portionof said handle, an electric motor, a casing therefor,

a flange on each end of said casing, one of said flanges of the casingbeing adapted to abut against the flange on the handle, a tube, a flangethereon, said last mentioned flange being adapted to engage the otherflange of the casing, ashaftextending thru said tube and operativclyconnected to saidmotor and a cleaner operatively connected with said ft.
